ceph: cephx protocol is vulnerable to replay attack

It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable.

glusterfs: Privilege escalation via gluster_shared_storage when snapshot scheduling is enabled

A privilege escalation flaw was found in gluster 3.x snapshot scheduler. Any gluster client allowed to mount gluster volumes could also mount shared gluster storage volume and escalate privileges by scheduling malicious cronjob via symlink.

qt: Malformed PPM image causing division by zero and crash in qppmhandler.cpp

An issue was discovered in Qt 5.11. A malformed PPM image causes a division by zero and a crash in qppmhandler.cpp.

qt5-qtimageformats: QTgaFile CPU exhaustion

An issue was discovered in Qt before 5.11.3. There is QTgaFile Uncontrolled Resource Consumption.

qt5-qtbase: QImage allocation failure in qgifhandler

An issue was discovered in Qt before 5.11.3. A malformed GIF image causes a NULL pointer dereference in QGifHandler resulting in a segmentation fault.

qt5-qtsvg: Invalid parsing of malformed url reference resulting in a denial of service

An issue was discovered in Qt before 5.11.3. A malformed SVG image causes a segmentation fault in qsvghandler.cpp.

A keystroke logging issue was discovered in Virtual Keyboard in Qt 5.7.x, 5.8.x, 5.9.x, 5.10.x, and 5.11.x before 5.11.3.

wawpack: Out-of-bounds read in WavpackVerifySingleBlock function leads to DoS

The function WavpackVerifySingleBlock in open_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (out-of-bounds read and application crash) via a crafted WavPack Lossless Audio file, as demonstrated by wvunpack.

wawpack: Infinite loop in WavpackPackInit function lead to DoS

The function WavpackPackInit in pack_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (resource exhaustion caused by an infinite loop) via a crafted wav audio file because WavpackSetConfiguration64 mishandles a sample rate of zero.

Qemu: bt: Integer overflow in Bluetooth routines allows memory corruption

The Bluetooth subsystem in QEMU mishandles negative values for length variables, leading to memory corruption.

gnuplot: buffer overflow in cairotrm_options function

An issue was discovered in cairo.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the cairotrm_options function. This flaw is caused by a missing size check of an argument passed to the "set font" function. This issue occurs when the Gnuplot pngcairo terminal is used as a backend.

gnuplot: buffer overflow with an arbitrary amount of data in the PS_options

An issue was discovered in post.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the PS_options function. This flaw is caused by a missing size check of an argument passed to the "set font" function. This issue occurs when the Gnuplot postscript terminal is used as a backend.

gnuplot: heap-based buffer overflow in df_generate_ascii_array_entry

An issue was discovered in datafile.c in Gnuplot 5.2.5. This issue allows an attacker to conduct a heap-based buffer overflow with an arbitrary amount of data in df_generate_ascii_array_entry. To exploit this vulnerability, an attacker must pass an overlong string as the right bound of the range argument that is passed to the plot function.

QEMU: 9pfs: crash due to race condition in renaming files

v9fs_wstat in hw/9pfs/9p.c in QEMU allows guest OS users to cause a denial of service (crash) because of a race condition during file renaming.

The WP Backup+ (aka WPbackupplus) plugin through 2018-11-22 for WordPress allows remote attackers to obtain sensitive information from server folders and files, as demonstrated by download.sql.

Qemu: 9pfs: Use-after-free due to race condition while updating fid path

hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an fid path while it is being accessed by a second thread, leading to (for example) a use-after-free outcome.

An issue was discovered in mod_alias_physical_handler in mod_alias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific mod_alias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character.

QEMU: ppc64: Out-of-bounds r/w stack access in pnv_lpc_do_eccb

The pnv_lpc_do_eccb function in hw/ppc/pnv_lpc.c in Qemu before 3.1 allows out-of-bounds write or read access to PowerNV memory.

QEMU: lsi53c895a: OOB msg buffer access leads to DoS

In Qemu 3.0.0, lsi_do_msgin in hw/scsi/lsi53c895a.c allows out-of-bounds access by triggering an invalid msg_len value.

ImageMagick: memory leak in WriteMSLImage of coders/msl.c

There is a memory leak in the function WriteMSLImage of coders/msl.c in ImageMagick 7.0.8-13 Q16, and the function ProcessMSLScript of coders/msl.c in GraphicsMagick before 1.3.31.
